  • Twisted coil wires.

    Has anyone ever tried to make a coil that had the wires twisted?

    Would there be any advantages?

    I'm about to wind a 36 inch coil which will be 16 strands and my plan is for 4 columns and 4 rows.

    That might have some similarities to basket winding, but without the capacitive advantage. However, in theory, it may be a way to gain some of the advantages of bifilar winding, without as much of the difficulty in winding it bifilar. I like bifilar, and Nikola Tesla explained it's benefits for solenoids. In order to wire in bifilar (series wound, and in the additive conficuration), you'd need to measure out two lengths of wire that will form the total coil, and divide that in two. It does not need to be cut in two yet. Then twist the two lengths together and wind, and in the end you then need to cut the midpoint. Then multimeter test to identify coils 1 and 2, and connect and join the end of coil 1 to the start of coil 2. This is one way to do the twisting of the wires, but it might not be what you had in mind

      Do you intend to connect the twisted wires in parallel? Or do you want to connect the twisted wires in series like people usually do, if they use network cables?

        I just wondered if it could be done with one continous piece of wire. The solution I came up with was to wrap around a core like a dowel rod.

          I think this would be extremely difficult with no benefit.

            "No benefit" that's a shame.
            If you think about it on a large coil it not that difficult in theory, would take more time, and be a bit fiddley.

              On a big coil you do what GeoMax suggested: use a multi-wire cable and solder the wires at a junction. Then you get to twist them any way you want. For a continuous-wound coil you would need a special (and probably expensive) winder. Twisting the wires will increase the overall length and probably increase the interwinding capacitance, neither of which are good. There would be almost no difference in the TX field.

                Yes I understand not worth the effort. Thanks
